STEAIYLSEPARATOR.

Specification of Letters Patent: Patented Aug. 31, igZiQ,

' Application filed December 31, 1919. Serial No. $8,614.

To all cohonyit may concern:

Be it known that in s, which form a part thereof.

' ly invention relates to steam separators of the kind employed for separating from the steam the entramed moisture which, in

modern types of boilers, amounts to from 1 per cent. to 2 per cent, and the object of my invention is to provide a separator of ample area andin which no pressure drop, due to will take place of the steam flow is rapidly changed to eifect the gravital separation of the water from the steam and in which efiective'pro vision is made for collecting the separated water by means which will prevent its beingrreentrained by the steam. I I

lie nature of my improvements'will bebest understood as explained in connection with the drawin s in which they are illustrated and in w ich- Fi ure 1 is a sectional. elevation taken throdgh one of the water collecting cham bers as on the line 1--1 of Fig. i.

Fig. 2 is an elevation of one of the end walls of the separator chamber. Fig. 3 an elevation taken through the boiler and separator in place therein as on the line 3-3 of Fig. 4, and

Fig. 4 a longitudinal sectional elevation of the separator taken as on the line 4-4: of Fig. 3.

A indicates the boiler and B the separator chamber, which, as shown is a rectangular boxlike structure secured in the steam space at the top of the boiler and having side walls B, B and end walls B B, the end walls being, as shown in Fig. 2, slotted and cut away to give passage to the baffles and gutters. C, are water collecting chambers located at the ends of the separator B and communicating through passages D, with the water space of the boiler. preference, the outer walls C of the cham- I, Josnrn J. Nam, a citizen of the United States of America,

chambers ber C are made readily removable. E is the outlet. passage from the separator and the boiler. 1 provide entrance passages from the steam space of the boiler to the bottom of the separator, as indicated at H, H; the bottom of the separator being made up of inclined plates F F, and G, g, and the entrance passages ii being bounded, as

shown, by plates F, F and G, g. This formation'of the bottom and entrance pas-i sages leaves gutters as indicated at F F and (i 9 which I prefer to partially cover by plates indicated at F F and G 9 andthese gutters communicate with the end C through passages L, L, and- M, M, formed in the end walls B The separator chamber is provided with a series of staggered baiiie plates so disposedas to compel the passing steam to make many changes of direction passing from the bot.- tom to the top of the separator, but so disposed also as to leave ample room for the body of steam passing through the separator Z5 and these to pass without pressure drop, baflies areinclined from'e'dge to edge so that the water deposited upon them will be bound to run downtoward their lower edges, plates, and preferably at the upper edges also, I provide tters arranged to receive the water deposited on and running down upon the surfaces of the bafiie plates, and by preference plates as donot at their upper edges contact with other" inclined plates, and where such contacting inclined plates meet 1 preferably provide a gutter 'below the apex formed edges to receive any by the passing steam,

The inclined baflying immediately by their contacting water which may, be driven to such apex.

fie plates contacting" at their upper edges are indicated at I and z, and the gutters formed at their lower edges-are indicated at and at the lower edges of the baffle 80 I also provide gutters on 85 the under sides of the upper edges of such .of the inclined bafiie J and J at their lower Y posited on the baflie plates and tends byv By preference, the end plates B are slotted, as shown in Fig. 2, to give passage to the ends of the baflie plates, although, of course,

it is not necessary that the plates should actually pass through these end plates, but in all cases passages are formed through the end 'plates for the gutters. Thus in Fig. 2 N indicates the slots formed for the lates I, z", and N, N the openings forme for the gutters I, I and 2'', 71 0 being openings for the passage of the gutters K. R indicates slots through which pass the end of the baflies J, B being openings for the gutters J, J and R and opening for the gutter J By preference, the baflie plates are inclined not only from edge to edge but from end to end, and, conveniently, they maybe inclined from the center of the separator chamber to the ends thereof, as indicated in Fig. 4:.

In operation the steam enters the separator box through the openings H,-H, and passes upward to the outlet opening E, having its direction rapidly and changed by its contact with the battles in the separator; the water in the steam is degravity to run into the gutters on their lower inclined edges and such water as by the pressure of the steam is forced toward the top edges of the bafiies is receivedin the gutters K or Water in the gutters can and will pass through the gutters and through the openings in the end walls B into the chamber and thence will pass through the pipes D to the water space of the boiler.

Having now described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. A steam separator consisting of a chamber adapted to be secured in the steam space of a boiler and having openings for the admission of steam at its bottom and anopening for the delivery of steam at its top, in combination with a system of staggered baffie plates extending from end to end of the chamber and formed with Water collecting gutters along their edges which gutters extend through an end Wall of the chamber, a closed chamber into which said gutters communicate and a drain pipe leading from said chamber to a point below the water level of the boiler.

, 2. A steam separator consistingof a chamber adapted to be secured in the steam space of a boiler and having openings for the admission of steam at its bottom and an opening for the delivery of steam at its top, in combination with a system of staggered baffle plates extending from end to end of the chamber and formed with water collecting gutters along their edges which gutters extend through the end Walls of the chamber, closed chambers into which said gutters abruptly communicate and drain pipes leading from said chambers to level of the boiler.

3.. A steam separator consisting of a chamber adapted to be secured in the steam space of a boiler and having openings for the admission of steam at its bottom and an opening for the delivery of steam at its top, in

points below the water combination With a system of staggered bafiie plates extending from end to end of the chamber, said baflie plates being inclined from edge to edge and formed with water collecting gutters alon their lower edges which gutters extend t rough an end wall of the chamber, a closed chamber with which said gutters communicate and a'drain' pipe leading from said closed chamber.

at. A steam separator consisting of a chamber adapted to be secured in the steam space of a boiler and having openings for the admission of steam at its bottom'and an open-' ing for the delivery of steam at itstop, in

drain pipe leading from said closed chamber.

5. A steam separator consisting of a chamber adapted to be secured in the steam space of a boiler and having openings for the admission of steam at its bottom and an opening for the delivery combination with a system of staggered baflie plates extendin from end to end of the chamber, said ba e plates being inclined from end to end and from edge to edge and formed with Water collecting gutters along their edges which gutters extend through an end wall of the chamber, a closed chamber with which said gutters communicate and a drain pipe leading from said closed chamber.

6. A steam separator consisting of a chamber adapted to be secured in the steam space of a boiler and having openings for the admission of steam at its bottom and an opening for the delivery of steam at its top, in combination with a system of staggered bafiie plates extending from end to end of the chamber, said bafiie plates being mainly in the form of inverted troughs, water collecting gutters extending along the edges of the baliie plates and through the end walls of the chamber, closed chambers into which said gutters open and drain pipes leading from said chamber to points below the water level of the boiler.
